PMIC for LS1012A

g_reshmi — Sat, 22 Jan 2022 11:43:49 GMT

Hi Team,

The PMIC used in all the reference board for LS1012A is VR5100 however it has gone obsolete. Can somebody point on a substitute for the same?

Also can I replace the DDR device. I mean would it be fine if I use some other DDR3L with same electrical specifications and functionalities or NXP/LS1012A supports specific DDR. If yes, kindly mention the specific DDR as well.

Regards,

Thanks Team.

This solves my search for PMIC. However DDR query still remains unsolved. Kindly have a look.

Hi Team,

Thanks for your response. However could you kindly provide the list of DDR3L specifically supported by NXP in their drivers?

There is no such list.
